Photovoltaic Potential and Insolation Maps (Canada)

Jump to: navigation, search
These interactive maps give estimates of the electricity that can be generated by grid-connected photovoltaic (PV) arrays without batteries and of the mean daily global insolation for any location in Canada. Insolation data was provided by the Data Analysis and Archive Division, Meteorological Service of Canada, Environment Canada. Maps are presented for each month and for the entire year, for six different PV array orientations: a sun-tracking orientation and five fixed South-facing orientations. Data can be obtained at any grid location by "querying" the maps.
